The $ u$THDM with the Inverse Seesaw Mechanisms


Abstract in English

In this paper, we combine the $ u$-Two-Higgs-Doublet-Model ($ u$THDM) with the inverse seesaw mechanisms. In this model, the Yukawa couplings involving the sterile neutrinos and the exotic Higgs bosons can be of order one in the case of a large $tan beta$. We calculated the corrections to the Z-resonance parameters $R_{l_i}$, $A_{l_i}$, $N_{ u}$, together with the $l_1 rightarrow l_2 gamma$ branching ratios, and the muon anomalous $g-2$. Compared with the current bounds and plans for the future colliders, we find that the corrections to the electroweak parameters can be contrained or discovered in much of the parameter space.
